CHARLES H. STRAFFIN, OF CHICAGO, ILLINOIS.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 459,599, dated September 15, 1891. i Application filed July 12, 1890. Serial No. 358,498. (No model.) l

To @ZZ whom, it may concern:

Be it known that I, CHARLES H. STRAFFIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Oil-Burner; and I hereby declare the following to be a full, clear, and exact description of the same.

- My invention relates to the class of oilburners for use without wicks in ordinary cooking stoves and ranges; and it is my object to provide a device of very simple and inexpensive construction whereby low grades of petroleum or fuel oils may be burned safely and easily by inexperienced persons in any kind of stoves or ranges, whether for cooking or heating.

My invention consists in the general construction of my improved device and in certain details of the said construction and combinations of the parts therein, all as hereinafter more particularly set forth.

.Referring to the drawings, Figure 1 is a perspective view of my improved device, showing the reservoir and a portion of the supply-pipe broken away to admit of representation upon the sheet; and Fig. 2, a View showing the right-hand conical convertingchamber in vertical section.

In the drawings, A A are iron convertingchambers in the form of truncated cones cored out hollow in casting and formed upon upward-curving saucers or flanges B B. Each of the conical converting-chambers A is provided upon its truncated top with a small orifice q, forming a burner, and has cast upon its face a female dovetail C, into which is fitted a male dovetail C, flattened horizontally at its head directly over the orifice q and at the proper height therefrom into a spreader or deflector C2, against which the iiame from the orifice q impinges and is forced out horizontally in every direction.

I do not confine myself, necessarily, to the particular form of support for the detlectors C2 herein set forth, as any other means whereby the said deflectors may be formed securely upon the converting-chambers A A will accomplish the same end. In practice, however, I prefer the dovetail form of attachment herein shown and described because of its simplicity and consequent inexpensive construction, there being no rivets or set-screws, and the parts, being all formed in the mold, do not even require to be filed before assembling them together.

The converting -chambers A A are connected by a tube D, fitted with a stop-cock E, having a long handle E to project out between the grate-bars on which my device rests when applied to a stove or range. A large pipe F is tapped atone end into one of the converting-chambers A, having no other connection with said converting-chambers, (whether there be one or two or morethan two chambers, as hereinafter described,) and communicates at the other end with anV oilsupply pipe r, running directly to an oil-tank. (Not shown in the drawings.) The pipe F is led directly beside the converting-chambers A A under the heat and flame from the deiiectors C2 and becomes much heated while the deviceis in use, but is of sufficient size to permit the oil'entering from the oil-supply pipe r to expand, thus forming what I call a primary converting-chamber.

A stopcock G governs the oilsupply through the oil-supply pipe 1" and is controllable by a hand-wheel s, to which is attached a hand t, showing by the readings on a dial or indicator when the supply of oil is entirely cut off and when properly open to admit oil in quantities sufficient for one or both burners.

In practice I construct my device of one, two, or more converting-chambers A A and burners q, may be necessary for the service required, ,the primary converting-chamber F being lengthened or shortened accordingly.

What I claim'as new, and desire to secure by Letters Patent, is

l. In an oil-burner, the combination, with conical converting-chambers A, provided each with a burner-orifice q, and deiiector C2,sup ported upon the face thereof vertically above the said burner-orifice q, of a primary converting-chamber F, communicating at one end with asuitable oil-supply and at the other end with the converting-chambers A, substantially as described.

2. In an oil-burner, the combination of conical converting-chambers A, provid ed each IOO with a, burner-orifice q, andafemale dovetail end With a suitable oil-supply, the Whole be- C on the 'face thereof supporting vertically ing arranged to operate substantially as and above the said burner-orifice g a, deeetor C2, for the purpose set forth.

carried upon a male dovetail C', with a pri- CHARLES H. STRAFFIN. mary converting-chamber F, communicating Witnesses: at; one end with Jhe converting-chambers A ROBERT E. MOSS,

and oontrollably communicating at the other GERHARD W. SCHRENK.
